TIRE.

Patented Nov. 1-, 1813.

Application filed October 28, 1912. Serial No. 728,185.

To all whom it may concern:

Be it known that I, Gor'rnrnn Anson, a citizen of the United States,residing at Mo Kees Rocks, in the county of Allegheny and State ofPennsylvania, have invented certain new and useful Improvements inTires, of which the following is a specification.

This invention relates to that class of resilient or cushion tires inwhich the resilient or cushion element is a series of metallic springswhich are interposed between a rigid inner rim and a yielding outer rimor tread which is composed of segments connected to each other by links.

It is the object of the invention to provide a simple and efficient tireof the kinc stated, and also one which can be readily applied to anyordinary wheel rim without altering the same.

These objects are attained by a novel combination and arrangement ofparts to be hereinafter described and claimed, reference being had tothe accompanying drawings, in which Figure 1 is an elevation of a wheelequipped with my improved tire, the parts being shown partly broken awayand in section, Fig. 2 is a cross-section on the line 2-2 of Fig. 1.Fig. 3 is a plan view of a fragment of the tire tread.

In the drawings, 10 denotes the inner rigid rim of the tire, the samecomprising a ring which is mounted on the rim 11 of an ordinary wheel soas to completely encircle the same. On one side of the ring is acontinuous flange 12 which fits the corresponding side of the wheel rimand is bolted thereto. The other side of the ring has an outstandingbase flange 13 onto which hooks a ring 1 1 which engages thecorresponding side of the wheel rim and is bolted thereto. By means oithe ring 1e, and the flange 12, the ring 10 is securely fastened to therim of the wheel. The fastening enables the tire to be easily andquickly applied or removed, and no alteration or modification in thestructure oi: the rim or other parts of the wheel is necessary.

The tread of the tire is composed of an annular series of segments 15which are spaced slightly endwise, and connected to each other on theirsides by links 16. The segments and their connecting links seat inholders 17 extending in an annular series around the tire, and composedof channeled plates carried by stems 18 which are countersunk in thebase portions of the holders, and pass loosely through apertures in thering 10, said apertures opening into a channel 19 to accommodate nuts 20screwed on the inner ends of the stems. In the side flanges of theholders, midway. between the ends thereof, are alined perforationsthrough which pass some of the pins 21 which connect the segments to thelinks 16, whereby the linked segments are prevented from creeping orrotating relative to the ring 10.

Between the holders 17 and the ring 10 is a rim 22 of leather or othersuitable fiexi ble material, and between this rim and the ring arelocated radially arranged coiled springs 23, which latter are coiledaround ring 10 has seats 24: for the inner ends of the springs, and tothe inner periphery of the rim 22 are secured seats 25 for the outerends of the springs. The rim 22 has openings through which the stems 18pass.

When the wheel is free from the ground, the tread extends concentricallywith respect to the ring 10, but when the wheel is on the ground andloaded, the circular shape of the tread is distorted by the flatteningout of the lower portion of the tread to a greater or less extentaccording to the load, this flattening out being resisted by thesprings. The tire therefore has a deformable or yielding tread which iscushioned by the springs. Adjustment of the springs is readily made bythe stems 18 and nuts 20.

The movement of the tread outward from the ring 10 is limited by shortchains 26 con nected at their ends to the sides of the ring 10 and theholders 17, respectively. In order to protect these chains, as well asthe springs 23, from dust, mud, etc, the space between the ring 10 andthe tread is closed up at the sides by a covering 27 of canvas or othersuitable flexible material secured to the ring 10 and to the holders 17.

I claim:

1. A wheel tire comprising a rigid rim, a ring encircling the rim, saidring having a channel in its inner periphery and radial aperturesopening from the channel through the outer periphery of the ring, meansfor securing the ring to the rim, a flexible rim encircling the ring inspaced relation, cushioning means between the ring and the flexible rim,an annular series of channeled plates the stems 18. The outer peripheryof the mounted on the outside of the flexible rim and spaced apartendwise, a tread mounted in the channels of sald plates, said treadbeing composed of segments which are;

spaced apart endwise, links connecting adjacent ends of said segments,certain of the connections between the links and the segments passingthrough the flanges of the channeled plates, ant? anchoring means forthe tread passing through the flexible rim and the aforesaid radialapertures into the ch annel of the ring.

2. A Wheel tire comprising a rigid rim, a ring encircling the rim, saidring having a apertures opening from the channel through the outerperiphery of the ring, means for securing the ring to the rim, aflexible rim encircling the ring in spaced relation, cushioning meansbetween the ring and the flexible rim, an annular series of channeledplates mounted on the outside of the flexible rim and spaced apartendWise, a tread mounted in. the channels of said plates, said treadbeing composed of segments which are spaced 25 apart endWise, linksconnecting adjacent ends of said segments, certain of the connectionsbetween the links and the segments )assine through the flames of thechanneled a I b ing through the flexible rim and the afore said radlalapertures. into the channel of the ring, and flexible connectionsbetween the ring and the channeled plates for limiting the outwardmovement of the latter. channel in its inner perlphery and radial Intestimony whereof I aflix my signature in presence of two witnesses.
